Protecting the Environment

Thich Nhat Hanh
Published in the Mindfulness Bell,#7 Autumn 1992

Many basic teachings in Buddhism can help us understand our interconnectedness with the environment. One of the deepest is the Prajnaparamita Vajracchedika Sutra (The Diamond that Cuts through Illusion). This sutra is a dialogue between the Venerable Subhuti and the Buddha. It begins with this question by Subhuti: “If daughters and sons of good families wish to give rise to the highest, most fulfilled, awakened mind, what should they rely on and what should they do to master their thinking?” This is the same as asking, “If I want to use my whole being to protect life, what methods and principles should I use?”

Thich Nhat HanhThe Buddha answered him, “However many species of living beings there are—whether born from eggs, from the womb, from moisture, or spontaneously; whether they have form or do not have form; whether they have perceptions or do not have perceptions; or whether it cannot be said of them that they have perceptions or that they do not have percep­tions, we must lead all these beings to the ultimate nirvana so that they can be liberated. And when this innumerable, immeasurable, infinite number of beings has become liberated, we do not, in truth, think that a single being has been liberated. Why is this so? If, Subhuti, a bodhisattva holds on to the idea that a self, a person, a living being, or a life span exists, that person is not an authentic bodhisattva.”

The Buddha’s answer can be summarized as, “We have to do our best to help every living being cross the river of suffering. But after all beings have arrived at the shore of liberation, no being at all has been carried to the other shore. If you are still caught up in the idea of a self, a person, a living being, or a life span, you are not an authentic bodhisattva.” Self, person, living being, and life span are the four notions that prevent us from seeing reality.

Life is one. We do not need to slice it into pieces and call this or that piece a self. What we call a self is actually made only of non-self elements. When we look at a flower, for example, we may think that it is different from “non-flower” things. But when we look more deeply, we see that everything else in the cosmos is in that flower. Without all of the non-flower elements—the sunshine, the clouds, the earth, minerals, heat, rivers, and consciousness—a flower cannot be. That is why the Buddha teaches that the self does not exist. What we call “self” is made only of non-self elements. Therefore, we have to throw away all distinctions between self and non-self.

Here is another example. You may think that you are not George Bush or Bill Clinton, but that is not correct. You are comprised entirely of “non-you” elements, among them the candidates for U.S. President. So you have to take good care of the Bush/Clinton elements in you. When you ask, “How can I stop being so angry at President Bush?” the first thing I will tell you is that Mr. Bush is you. Mr. Bush is a non-you element in you. The trees are also non-you elements. If you look deeply, you will see all of these non-you elements, and you will know that you have to take care of George Bush and the trees that are in you. We cannot say, “I am separate and unique. I am not responsible for any of these things.” Instead, we must learn to say, “By taking good care of myself, I take care of you. And by taking good care of you, I take care of myself.” How can anyone work to protect the environment without this kind of insight?

The second notion that prevents us from seeing reality as it is is the notion of a person, a human being. We usually discriminate between humans and non-humans, thinking that we are more important than other species. But since we humans are made of non-human elements, to protect ourselves we have to protect all of the non-human elements. There is no other way. If you think, “God created man in his own image and He created other things for man to use,” you are already making the discrimination that man is more important than other things. When we see that humans have no self, we see that to take care of the environment (the non-human elements) is to take care of humanity. The best way to take good care of men and women so that they can be truly healthy and happy is to take care of the environment.

I know ecologists who are not happy with their partners.They work hard to improve the environment, partly to escape their family life. If someone is not happy within himself, how can he help the environment? That is why the Buddha teaches that to protect the non-human elements is to protect humans, and to protect humans is to protect non-human elements.

The third notion we have to break through is the notion of a living being. We think that we living beings are different from inanimate objects, but according to the principle of interbeing, living beings are comprised of non-living-being elements. When we look into ourselves, we see minerals and all other non-living-being elements. Why discriminate against what we call inanimate? To protect living beings, we must protect the stones, the soil, and the oceans. Before the atomic bomb was dropped on Hiroshima, there were many beautiful stone benches in the parks. As the Japanese were rebuilding their city, they discovered that these stones were dead, so they carried them away and buried them. Then they brought in live stones. Do not think these things are not alive. They are alive. Atoms are always moving. Electrons move at nearly the speed of light. According to the teaching of Buddhism, these atoms and stones are consciousness itself. That is why discrimination by living beings against non-living beings should be discarded.

The last notion is that of a life span. We think that we have been alive since a certain point in time and that prior to that moment, our life did not exist. This distinction between life and non-life is not correct. Life is made of death, and death is made of life. We have to welcome death, because it makes life possible. The cells in our body are dying every day, but we don’t organize funerals for them. The death of one cell allows for the birth of another. Life and death are two aspects of the same reality. We must learn to die peacefully so that others may live. This deep meditation brings forth non-fear, non-anger, and non-despair, the strengths we need for our work. With non-fear, even when we see that a problem is huge, we will not burn out. We will know how to make small, steady steps. If those who work to protect the environment contemplate these four notions, they will know how to be and how to act.

In another beautiful Buddhist text, The Avatamsaka (“Adorning the Buddha with Flowers”) Sutra,the Buddha continues to elaborate his insights concerning our unity with our environment. In this sutra, the word “interpenetration” is introduced. Please meditate with me on the “Ten Penetra­tions.”

The first is, “All worlds penetrate a single pore. A single pore penetrates all worlds.” Look deeply at a flower. It may be tiny, but the sun, the clouds, and everything else in the cosmos penetrate it. Nuclear physicists say very much the same thing: one electron is made by all electrons; one electron is in all electrons.

The second penetration is, “All living beings penetrate one body. One body penetrates all living beings.” When you kill a living being, you kill yourself and everyone else as well.

The third is, “Infinite time penetrates one second. One second penetrates infinite time.” Ksanameans the shortest period of time, actually much shorter than a second.

The fourth penetration is, “All Buddhist teachings pen­etrate one teaching. One teaching penetrates all Buddhist teachings.” As a young monk, I had the opportunity to learn this important sentence: “Buddhism is made of non-Buddhist elements.” So I always respect non-Buddhist elements. Whenever I study Christianity or Judaism, I find the Buddhist elements in them, and vice versa. All Buddhist teachings penetrate one teaching, and one teaching penetrates all Buddhist teachings. We are free.

The fifth penetration is, “Innumerable spheres enter one sphere. One sphere enters innumerable spheres.” A sphere is geographical space. Innumerable spheres penetrate into one particular area. And one particular area enters into innumer­able spheres. It means that when you destroy one area, you destroy every area. When you save one area, you save all areas. One student asked me, “Thay, there are so many urgent problems, what should I do?” I said, “Take one thing and do it very deeply and carefully, and you will be doing everything at the same time.”

The sixth penetration is, “All sense organs penetrate one organ. One organ penetrates all sense organs”—eye, ear, nose, tongue, body, and mind. To take care of one means to take care of many. To take care of your eyes means to take care of the eyes of innumerable living beings.


The seventh penetration is, “All sense organs penetrate non-sense organs. Non-sense organs penetrate all sense organs.” Not only do non-sense organs penetrate sense organs, they also penetrate non-sense organs. There is no discrimination. Sense organs are made of non-sense-organ elements. That is why they penetrate non-sense organs. This helps us remember the teaching of the Diamond Sutra.

The eighth penetration is, “One perception penetrates all perceptions. All perceptions penetrate one perception.” If your perception is not accurate, it will influence all other perceptions in yourself and others. Suppose a bus driver has an incorrect perception. We know what may happen. One perception penetrates all perceptions.

The ninth penetration is, “Every sound penetrates one sound. One sound penetrates every sound.” This is a very deep teaching. We need to understand one sound or one word in order to understand all sounds and all words.

The tenth penetration is, “All times penetrate one time. One time penetrates all times”—past,present, and future. In one second, you can find the past, present, and future. In the past, you can see the present and the future. In the present, you can find the past and future. In the future, you can find the past and present. They “inter-contain” each other. Space contains time, time contains space. In the teaching of interpenetration, one determines the other, the other determines this one. Once we realize our nature of “interbeing,” we will stop blaming and killing, because we will know that we “inter-are.”

Interpenetration is an important Dharma door, but it still suggests that things that are outside of one another penetrate into each other. Interbeing is a step forward. You are already inside, so you don’t have to enter it anymore. In contemporary nuclear physics, people talk about implicit order and explicit order. In the explicit order, things exist outside of each other—the table outside of the flower, the sunshine outside of the cypress tree. Another way of looking at things is to see that they are inside each other—the sunshine inside the cypress tree. Interbeing is the implicit order. To practice mindfulness and to look deeply into the nature of things is to discover the true nature of interbeing. You will find peace, and you will develop the strength that enables you to be in touch with everything. With this understanding, you can easily sustain the work of loving and caring for the Earth and for each other for a long time.

This essay is adapted from a talk given by Thich Nhat Hanh at the Retreat for Environmentalists in March 1991 in Malibu, California. These teachings were developed during the three-week June 1992 retreat at Plum Village on “Vipassana (Looking Deeply) in the Mahayana Tradition.” Tapes of all of these lectures are available from Plum Village or Parallax Press. The teachings on the Diamond Sutra can also be found in Thay’ s book, The Diamond that Cuts through Illusion (Parallax Press).
